Near-perfect sRGB coverage is relatively common, especially with OLEDs. Now the concern is AdobeRBG, DCI-P3, and Rec.2020 coverage* -- which are still generally lagging (basically nothing short of some $$$$$ laser projectors are anywhere close to full coverage of Rec.2020, which covers ~75% of all visible colors and is an ambitious forward-looking colorspace) .

  * sRGB < AdobeRGB ~= DCI-P3 < Rec.2020
